Concrete crack repairing device and method

Abstract

The invention relates to a concrete crack repairing device and method and relates to the technical field of concrete structures. The problems that complete crack filling is hardly ensured and the filling effect is poor are solved. The concrete crack repairing device comprises multiple concrete prefabricated pipes driven into a crack and further comprises multiple grout guide hoppers. Two grout guide grooves are symmetrically formed in the peripheral side of each of the grout guide hoppers and the concrete prefabricated pipes. The multiple grout guide hoppers are commonly connected with multiple grout pressing plates. The concrete crack repairing method includes the steps that S1, crack detection is conducted; S2, a drilling point is marked; S3, drilling is conducted; S4, crack cleaning isconducted; S5, pipe burying is conducted; S6, the grout guide hoppers and the grout pressing plates are placed; S7, water testing is conducted; S8, primary grouting is conducted; S9, secondary grouting is conducted; and S10, chiseling and floating are conducted. By means of the concrete crack repairing device and method, the grouting condition in the crack can be conveniently observed in real timein the grouting process, it is ensured that the crack is filled, after grouting is completed, operation is easy and convenient, construction is easy, repairing is fast, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of concrete structures, in particular to a concrete crack repairing device and repairing method. Background technique [0002] During the construction and use of buildings, due to structural stress conditions, foundation deformation, temperature control and other factors, cracks will appear in the concrete structure. When the cracks are wide or develop and endanger the durability of the structure, it is necessary to carry out Repair and seal the cracks to prevent the intrusion of water vapor, chemicals and carbon dioxide. [0003] The existing Chinese patent whose authorized notification number is CN206144187U proposes a concrete crack repair device, including a water sprayer for spraying water, a dry powder sprayer for spraying cement dry powder, and an adjustable vibration for the dry powder sprayer. The frequency vibration device, the control system for controlling the operation of the equipment, the equ...

Problems solved by technology

[0004] The above existing technical solutions have the following defects: in the process of use, the depth of cracks is judged by manual observation, and the cracks are repaired by artificial prediction. Since the cracks are irregular in shape, it is difficult to ensure that the cracks are completely filled by manually passing through the device. , the filling effect is poor
